A type of attack employing both direct attack and indirect attack methods.
An apparatus-mounted master stream device that is intended to flow large amounts of water directly onto a fire or exposed building.
Firefighting operations involving the application of extinguishing agents directly onto the burning fuel.
A nozzle mounted on the end of an aerial device that is capable of delivering large amounts of water onto a fire or exposed building from an elevated position.
Elevated master stream device
The use of a solid object, such as a wall or ceiling, to break apart a stream of water, creating more surface area on the water droplets and thereby causing the water to absorb more heat.
Indirect application of water

A monitor that is fed by hose and that holds and directs a nozzle while attached to the rungs of a vehicle-mounted aerial ladder.
A large-capacity nozzle that can be supplied by two or more hoselines or fixed piping. Such devices include deck guns, portable ground monitors, and elevated streams and commonly flow between 350 and 1,500 GPM.
Master stream device
A monitor that can be lifted from a vehicle mounted bracket and moved to an operating position on the ground by not more than two people.
A stream made by using a smooth-bore nozzle to produce a penetrating stream of water.
The material covering the gap between the edge of the roof and the exterior wall of the house. The soffits in most modern houses contain a system of vents to maintain an air flow to the attic area. Some attics may have sealed soffits to create a conditioned air space for energy conservation.
A stream made by using an adjustable nozzle to provide a straight stream of water.
An offensive fire attack initiated by an exterior, indirect handline operation into the fire compartment to initiate cooling while transitioning into the interior direct fire attack in coordination with ventilation operations.

Venting smoke and heat out a window
In an direct fire attack, how is the water actually discharged onto the fuel?
Directed onto the base of the fire
Where are defensive firefighting operations conducted from?
Water should be flowed during an indirect attack until:
The room begins to darken

Offensive or defensive
What is the larges flow in GPM that a master stream device can generate?
2000 or more GPM
